Introduce NDRs for adding links to other vocabs about spec-jsonld HOT 4 CLOSED

We probably want to support some or all of these references. To be continued.

Encouragement to please add comments here for further discussion...

from spec-jsonld.

there are a few different ideas here.

• equivalence to external vocabularies. We can do that (e.g. unece "party" is equivalent to schema.org "organisation"
• meaningful specialisations of uncefact generic terms (eg "rail" is a type of "transportMeans"). There are potentially two sub-types of this
  • when there exists a standard uncefact codelist that enumerates the specialised types then our NDR can just say "make a subclass for each term in the codelist"
  • when there is no term for the specialisation (eg billofLadingNumber as subtype of identifer). this , as a technical project maybe doesnt have the authority to define new semantics. However maybe we can define a governance mechanism for such extensions to be proposed, reviewed, and accepted/rejected.

This really does boil down to a vocabulary governance process. I think we need to "show the way" with a more decentralised governance process

We will do this with english sentences in the section:
